Description
The Kseibi HSS Step Drill Bit range gives you a practical way to drill and enlarge holes with one bit. Made from #4241 high speed steel and finished with black oxide, these step bits are designed for smooth, controlled cutting across a choice of inch-based size ranges. Clearly marked step sizes on the bit help you stop at the diameter you need, making setup faster and reducing guesswork on the job.
With options including 1/8 inch to 1/2 inch in 13 steps, 3/16 inch to 1/2 inch in 6 steps, 1/4 inch to 3/4 inch in 9 steps, 3/16 inch to 7/8 inch in 12 steps, 1/4 inch to 1-3/8 inch in 10 steps, and 7/8 inch to 1-3/8 inch in 5 steps, there is a size range to suit everything from smaller pilot enlargements to wider openings. The stepped profile is ideal when you want one tool to cover multiple diameters without changing bits repeatedly.
The image shows a hex shank design for secure chuck grip, helping the bit stay planted during drilling. This makes the range a handy choice for installers, fabricators, maintenance work and general workshop use where speed, convenience and precise diameter control matter. Depending on the selected variant, the bit is supplied in double blister card packing, while the 7/8 inch to 1-3/8 inch version is listed with plastic case packing.
If you need a compact, versatile drilling solution in inch increments, Kseibi step drill bits offer a straightforward combination of range, readable sizing and durable HSS construction.
